2. For items not provided for by the City’s standard details, a detail shall be provided by the designer and approved by the City.

3. An electronic copy, on compact disc (CD), of the City’s standard details is available for purchase through the City’s Engineering Division. These standard details are available in AutoCAD format.

Section II. Land Disturbance Plan Implementation

A land disturbance permit must be applied for and issued by the City, and a pre-construction meeting held, prior to the start of any land disturbing activity within the City of Woodbury.

A. Implementation of SWPPP

1. All required permanent and temporary erosion and sediment control measures shall be installed prior to the start

of any land disturbing activities. The City Engineer must be notified upon completion of the installation of the required erosion control facilities and prior to any land disturbing activity being commenced. The contractor is responsible to schedule an on-site pre-construction meeting with the City Engineer.

2. Permanent and temporary sedimentation basins shall be constructed and made operational currently with the

start of land disturbance that is upgradient of the area. If the owner proves to the City that it is not practical to construct the basins at the beginning of construction, other acceptable means of sediment control must be provided.

3. Any additional erosion and sediment control measures deemed necessary by the City before, during or after the

land disturbance activities begin shall be installed by the owner at their expense.

4. Prior to the issuance of building permits, all necessary erosion control devices must be in place and functioning. The City shall inspect the site to determine its suitability for building activities. If the public utilities have not been installed at this point, it may be necessary to withhold building permits for various lots to allow the contractor adequate space to perform this work. Building sites shall have, at a minimum, perimeter erosion and sediment controls and a rock construction entrance installed.

B. Inspection and Maintenance

1. Construction sites shall be inspected at minimum once every seven (7) days and within 24-hours after a rainfall event greater than one-half (0.5) inch in 24-hours. The owner or his representative shall make inspections.

Note: Inspections may be completed concurrently with the requirements of the NPDES Construction Activity

storm water permit requirements. Additional inspections may also be performed by the City on an as needed

basis.

2. A written record shall be completed for each inspection including date, amount of rainfall if greater than one-half (0.5) inch, name of inspector, findings, and corrective actions required. Inspections shall be recorded on

Note: Inspection records may be completed concurrently with the requirements of the NPDES Construction

Activity storm water permit requirements.

3. Any deficiencies found as a result of an inspection shall be repaired or corrected within 24-hours or as soon as field conditions allow access. If certain repairs cannot be made within 24-hours, a detailed plan and schedule for repairs shall be prepared and presented to the City for approval.

4. The storm water pollution prevention plan shall be modified as deemed necessary based on actual site conditions. Additional erosion and sediment control measures may be necessary based on any modifications to the plan.

5. All erosion control measures shall be used and maintained for the duration of project until final stabilization has been achieved. If construction operations or natural events damage or interfere with any erosion control measures, they shall be restored to serve their intended function at the end of each day or as soon as field conditions allow access.

6. Additional erosion and sediment control measures shall be added as necessary to adequately protect the natural resources of the City. The temporary and permanent erosion control plans shall be revised as needed based on current site conditions and to comply with all applicable requirements.

7. All sedimentation occurring in storm sewers, ditches, lakes, ponds and wetlands shall be removed prior to, during or after the completion of land disturbing activities as directed by the City.

8. Erosion control facilities shall be installed and maintained around the perimeter of all lakes, ponds and wetlands within or adjacent to the area to be disturbed until the area tributary to the lake, pond or wetland is restored and accepted by the City.

9. Rock construction entrances shall be constructed at all entrances into the site. These entrances shall be constructed and maintained as necessary to prevent tracking from the site.

10. Temporary erosion control measures and devices shall be removed only as approved by the City. Removal of all temporary measures shall be completed by the owner at his cost.

11. Soils washed onto or tracked from the site by motor vehicles and equipment shall be cleaned daily from paved roadway surfaces throughout the duration of construction.

ORDINANCE NO. 1749

AN ORDINANCE OF THE CITY OF WOODBURY, WASHINGTON COUNTY, MINNESOTA PROVIDING THAT THE WOODBURY CITY CODE BE AMENDED BY AMENDING CHAPTER 7, GRADING AND EXCAVATION. THE CITY COUNCIL OF THE CITY OF WOODBURY, WASHINGTON COUNTY, MINNESOTA DOES HEREBY ORDAIN: That Chapter 7 of the City Code of the City of Woodbury is hereby amended to read as follows:

CHAPTER 7: LAND DISTURBANCE AND EROSION AND SEDIMENT CONTROL ORDINANCE

Sec. 7-1. Purpose. The purpose of this chapter is to safeguard life, limb, property, public welfare and the environment by regulating land disturbing activities and controlling erosion and sedimentation within the city. Sec. 7-2. Scope. This chapter sets forth rules and regulations to control land disturbing activities, erosion and sedimentation; establishes the requirements and administrative procedure for issuance of permits; provides for review of plans and inspection of land disturbing activities; and provides procedures for enforcement of noncompliance. Sec. 7-3. Definitions. For the purposes of this chapter the definitions listed hereunder shall be construed as specified in this section. Applicant is any person or group that applies for a permit to allow land disturbing activities. Applicant also means that person's agents, employees, and others acting under this person's or group’s direction. The term “applicant” also refers to the permit holder or holders and the permit holder’s agents, employees, and others acting under this person's or group’s direction. Approval shall mean the proposed work or completed work conforms to this chapter in the opinion of the city. As-graded is the extent of surface conditions on completion of grading. Bedrock is in-place solid rock. Bench is a relatively level step excavated into earth material on which fill is to be placed. Borrow is earth material acquired from an off-site location for use in grading on a site. City is the administrative staff, or its agent, of the City of Woodbury. City council is the elected governing board of the City of Woodbury. Civil engineer is a professional engineer licensed by the Minnesota Board of Architecture, Engineering, Land Surveying, Landscape Architecture, Geoscience, and Interior Design to practice in the field of civil engineering. Civil engineering is the application of the knowledge of the forces of nature, principles of mechanics and the properties of materials to the evaluation, design and construction of civil works for the beneficial uses of mankind.

2

Common plan of development or sale is a contiguous area where multiple separate and distinct land disturbing activities may be taking place at different times, or on different schedules, but under one proposed plan including but not limited to mass site grading, utility installation, street construction and home or building construction. This item is broadly defined to include design, permit application, advertisement or physical demarcation indicating that land disturbing activities may occur.

Compaction is the densification of a soil by removal of air, which requires mechanical energy. Discharge is the release, conveyance, channeling, runoff, or drainage, of storm water, including snowmelt and dewatering water, from a site.

Earth material is any rock, natural soil or fill and/or any combination thereof. Engineering geologist is a geologist experienced and knowledgeable in engineering geology. Engineering geology is the application of geologic knowledge and principles in the investigation and evaluation of naturally occurring rock and soil for use in the design of civil works. Erosion is the wearing away of the ground surface as a result of the movement of wind, water and/or ice. Erosion control refers to methods employed to prevent erosion. Examples include soil stabilization practices, horizontal slope grading, temporary or permanent cover, and construction phasing.

Excavation is the mechanical removal of earth material. Fill is a deposit of earth material placed by artificial means. Final stabilization means that all soil disturbing activities on the site or common plan of development or sale have been completed, and that a uniform (evenly distributed, e.g., without large bare areas) perennial vegetative cover with a density of at least eighty (80) percent of the cover for unpaved areas and areas not covered by permanent structures has been established, or equivalent permanent stabilization measures have been employed, and that all temporary erosion control devises are removed, including silt fence, temporary sedimentation basins, and temporary standpipes. Simply sowing grass seed and/or mulch is not considered final stabilization. Final stabilization of a “common plan of development or sale” includes completion of building or home construction along with final restoration of all yards and adjacent drainage ways. Geotechnical engineer is a professional engineer licensed by the Minnesota Board of Architecture, Engineering, Land Surveying, Landscape Architecture, Geoscience, and Interior Design to practice in the field of geotechnical engineering. Geotechnical engineering is the application of the principles of soils mechanics in the investigation, evaluation and design of civil works involving the use of earth materials and the inspection and/or testing of the construction thereof. Grade is the vertical location of the ground surface. Existing grade is the grade prior to grading or land disturbing activities. Rough grade is the stage at which the grade approximately conforms to the approved plan. Finish grade is the final grade of the site, within 0.2 feet, that conforms to the approved plan. Grading is any excavating or filling or combination thereof. Hydric soils are soils that are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper layers.

3

Hydrophytic vegetation is macrophytic (large enough to be observed by the naked eye) plant life growing in water, soil or on a substrate that is at least periodically deficient in oxygen as a result of excessive water content. Land disturbance activity is any land change that may result in soil erosion from water or wind and the movement of sediments into or upon waters or lands within this government’s jurisdiction, including construction, clearing and grubbing, grading, excavating, transporting and filling of land. Permanent controls are long-term methods employed to prevent erosion and sedimentation. Examples of such protection are swales, ponds, sediment basins, turf reinforcement mats, storm sewer systems, and riprap. Permanent cover means “final stabilization.” Examples include grass, gravel, asphalt, and concrete. See also the definition of “final stabilization.” Permit is a written warrant or license granted for land disturbing activities. Sediment is the product of an erosion process; solid material both mineral and organic, that is in suspension, is being transported, or has been moved by water, wind, or ice, and has come to rest on the earth's surface either above or below water level. Sedimentation is the process or action of depositing sediment. Sediment control is the methods employed to prevent sediment from leaving a site. Examples of sediment control practices are silt fences, sediment traps, earth dikes, drainage swales, check dams, subsurface drains, pipe slope drains, storm drain inlet protection, and temporary or permanent sedimentation basins. Site is any lot or parcel of land or contiguous combination thereof, under the same ownership, where a land disturbing activity is performed or permitted. Slope is an inclined ground surface the inclination of which is expressed as a ratio of horizontal distance to vertical distance. Soil is naturally occurring superficial deposits overlying bedrock. Stabilized shall mean the exposed ground surface after it has been covered by perennial vegetation, sod, erosion control blanket, riprap, pavement or other material that prevents erosion. Simply sowing grass seed is not considered stabilization. Storm water as defined under Minnesota Rule 7077.0105, subpart 41b storm water, “means precipitation runoff, storm water runoff, snow melt runoff, and any other surface runoff and drainage.” Storm water pollution prevention plan is a joint storm water and erosion and sediment control plan that is a document containing the requirements of this chapter and the City of Woodbury Land Disturbance Plan and Implementation Requirements, that when implemented will decrease soil erosion on a parcel of land and off-site nonpoint pollution. It involves both temporary and permanent controls. Temporary controls are short-term methods employed to prevent erosion and sedimentation. Examples of such protection are silt fence, temporary sediment basins, check dams, straw, mulch, erosion control blankets, wood chips, and erosion netting. Terrace is a relatively level step constructed in the face of a graded slope surface for drainage and maintenance purposes. Wetlands as defined in Minnesota Rules 7050.0130, subpart F, are those areas that are inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally

4

include swamps, marshes, bogs, and similar areas. Constructed wetlands designed for wastewater treatment are not waters of the state. Wetlands must have the following attributes: (1) A predominance of hydric soils;

(2) Inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support a

prevalence of hydrophytic vegetation typically adapted for life in a saturated soil condition; and (3) Under normal circumstances support a prevalence of such vegetation. Sec. 7-4. General conformance. The owner of a site or common plan of development or sale shall be responsible for maintaining any land disturbing activity in such a way as not to create a hazard to life and limb; or endanger the environment; or endanger property; or adversely affects the safety, use or stability of a property, public way or drainage channel; or deposit sediment on or into adjacent properties, right-of-ways, drainage systems or wetlands until final stabilization, as defined in section 7-3, has been achieved. Whenever the city determines that any land disturbing activity has become a hazard to life and limb; or endangers the environment; or endangers property; or adversely affects the safety, use or stability of a property, public way or drainage channel; or deposits sediment on or into adjacent properties, right-of-ways, drainage systems or wetlands, the owner of the property upon which the land disturbance activity is located, or other person or agent in control of said property, upon receipt of notice in writing from the city, shall within the period specified therein repair or eliminate such land disturbing activity so as to eliminate the hazard and be in conformance with the requirements of this code. The city may inspect any property for conformance with this chapter. Sec. 7-5. Land disturbance permit required. No person shall do any land disturbing activity without first having obtained a land disturbance permit from the city, except for the following:

(1) A land disturbing activity which meets all of the following requirements:

a. Is located in an isolated, self-contained area. b. There is no danger apparent to private or public property. c. Does not infringe upon any wetland or ponding area or impede any drainage course. d. The total area of disturbance is less than one (1) acre and is not part of a common plan of development or

sale that is equal to or greater than one (1) acre. e. The total volume of earth material disturbed, stockpiled, disposed of, or used as fill does not exceed fifty

(50) cubic yards. f. Is an excavation that is less than two (2) feet in depth and does not create a cut slope greater than five (5)

feet in height, or is steeper than two (2) horizontal to one (1) vertical or is a fill that is less than two (2) feet in depth and place on natural terrain with a slope flatter than three (3) horizontal to one (1) vertical, or is less than three feet in depth, not intended to support structures.

These types of activities may include the installation and maintenance of home gardens, minor landscaping, fences, signs and mailboxes.

(2) An excavation below finished grade for basements and footings of a building, retaining wall or other structure

authorized by a valid building permit. This shall not exempt the requirement for a permit for a land disturbing activity resulting from the material from such excavation nor exempt any excavation having an unsupported height greater than 5 feet after the completion of such structure.

(3) Cemetery graves. (4) Refuse disposal sites controlled by other regulations, laws or City Code.

5

(5) Excavations for wells or tunnels or utilities controlled by other regulations, laws or City Code. (6) Mining, quarrying, excavating, processing, stockpiling of rock, sand, gravel, aggregate or clay where

established and provided for by law or ordinance. This shall not exempt these types of activities from the special use permit requirements set forth by City Code.

(7) Tilling, planting, or harvesting of agricultural, horticultural or silvicultural (forestry) crops. This shall not

exempt these types of activities from the special use permit requirements set forth by City Code. (8) Exploratory excavations and borings under the direction of geotechnical engineers or engineering geologists.

(9) Emergency work necessary to protect life, limb, or property.

(10) City, county, state or federal agency projects whose plans and specifications meet the requirements of this

ordinance and are reviewed and approved by the city under a separate process. Exemption from the permit requirements of this chapter shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of this chapter. Sec. 7-6. Land disturbance permit requirements.

(a) Permits required. Except as exempted in section 7-5, no person shall do any land disturbing activity without first obtaining a land disturbance permit from the city. A separate permit shall be required for each site or common plan of development or sale, and may cover both excavations and fills. Changes or deviation from previously reviewed plans require an amended permit be applied for and approved before the work is performed.

(b) When permit may be applied for and issued. A land disturbance permit may be applied for at any time. A land disturbance permit may not be issued until after the city council has granted the applicant a preliminary plat, site plan or equivalent approval of the site and all permit conditions have been completed to the satisfaction of the city. For individual isolated land disturbing activities, the city may grant a land disturbance permit without city council approval of a preliminary plat, site plan, or equivalent approval.

(c) Application. To obtain a permit, the applicant shall first file an application in writing on a form furnished by the city for that purpose. Every such application shall:

(j) Engineering geology report. The engineering geology report, when required, shall include an adequate description of the geology of the site, conclusions and recommendations regarding the effect of geologic conditions on proposed development, and opinions and recommendations covering the adequacy of sites to be developed by the proposed grading. Recommendations included in the report and reviewed by the city shall be incorporated in the grading plans or specifications.

(k) Review and issuance of permit. The application, plans, specifications, computations and other data filed by an applicant for permit shall be reviewed by the city. Such plans may be reviewed by other agencies to verify compliance with any applicable laws under their jurisdiction. If the city finds that the work described in an application for a permit and the plans, specifications and other data filed therewith conform to the requirements of this chapter and other pertinent laws and ordinances, and that the fees and security requirements for said permit have been provided, the city may issue a permit to the applicant. When the city issues the permit where plans are required, the city shall endorse in writing or stamp the plans and specifications "Reviewed". Such reviewed plans and specifications shall not be changed, modified or altered without authorization from the city, and all work shall be done in accordance with the reviewed plans. The city may issue a provisional permit for a land disturbing activity before the entire plans and specifications have been submitted or reviewed, provided adequate information and detailed statements have been filed complying with all pertinent requirements of this chapter. The holder of such provisional permit shall proceed at his own risk without assurance that the permit for the entire project will be granted. The issuance of a land disturbance permit by the city does not exempt the applicant from the requirements and permitting authority of other agencies having jurisdiction over the work performed.

(l) Retention of plans. One (1) set of reviewed plans, specifications and computations shall be retained by the city for a period of not less than one (1) year from date of completion of the work covered therein; and one (1) set of reviewed plans and specifications shall be returned to the applicant, and said set shall be kept on the site of the building or work at all times during which the work authorized thereby is in progress.

(m) Validity of permit. The issuance or granting of a permit or approval of plans, specifications and computations shall not be construed to be a permit for, or an approval of, any violation of any of the provisions of this chapter or of any other ordinance of the city. No permit presuming to give authority to violate or cancel the provisions of this chapter shall be valid. The issuance of a permit based upon plans, specifications and other data shall not prevent the city from thereafter requiring the correction of errors in said plans, specifications and other data, or from preventing land disturbing activities being carried on thereunder when in violation of this chapter or of any other ordinance of the city.

(n) Expiration. Every permit issued by the city under the provisions of this chapter shall expire by limitation and become null and void if the work authorized by such permit is not commenced within ninety (90) days from the date of issuance of such permit, or if the work authorized by such permit is suspended or abandoned at any time after the work

8

is commenced for a period of one hundred eighty (180) days. Before such work can be recommenced, a new permit shall be first obtained to do so, and the fee therefore shall be one-half the amount required for a new permit for such work, provided no changes have been made or will be made in the original plans and specifications for such work; and provided further that such suspension or abandonment has not exceeded one (1) year. In order to renew action on a permit after expiration, the permittee shall pay a new full permit fee. Any permittee holding an unexpired permit may apply for an extension of the time within which the permittee may commence work under that permit when the permittee is unable to commence work within the time required by this section for good and satisfactory reasons. The city may extend the time for action by the permittee for a period not exceeding one hundred eighty (180) days upon written request by the permittee showing that circumstances beyond the control of the permittee have prevented action from being taken. No permit shall be extended more than once.

(o) Suspension or revocation. The city may, in writing, suspend or revoke a permit issued under the provisions of this chapter whenever the permit is issued in error or on the basis of incorrect information supplied, or is found to be in violation of any ordinance or regulation or any of the provisions of this chapter. Sec. 7-7. Land disturbance permit fees.

(a) Generally. Fees shall be charged in accordance with the provisions of this section or shall be as set forth in the fee schedule adopted by the city council by ordinance.

(b) Plan Review Fees. When a plan or other data is required to be submitted, a plan review fee shall be paid at the time of submitting plans and specifications for review. Said plan review fee shall be as established by the city council by ordinance.

(c) Land Disturbance Permit Fees. A fee for each land disturbance permit shall be paid to the city as established by city council by ordinance. Sec. 7-8. Land disturbance permit financial security.

(a) Generally. The city will require financial security in such form and amounts as deemed necessary to assure that the work, if not completed in accordance with the reviewed plans and specifications, will be corrected to eliminate conditions posing a danger to public health, safety and welfare, adjacent property and the environment. The security shall be in the form of a surety bond, cash bond, or an irrevocable letter of credit. The financial security must be in place prior to any work. The amount of financial security required will be calculated based on the work detailed in the plans and specifications. The city may require a portion of the security to be provided as a cash escrow based on the proposed work.

(b) Action against financial security. The city may act against the financial security, if any of the following conditions exist. The city shall use funds from this security to finance any corrective or remedial work undertaken by the city or a contractor under contract with the city and to reimburse the city for all direct cost incurred in the process of remedial work including, but not limited to, staff time and legal fees.

(1) The applicant ceases land disturbing activities and abandons the work site prior to the completion of the city approved plans and specifications.

(2) The applicant fails to conform to any city approved plans and specifications, or related supplementary instructions including permit conditions of approval and corrective action notices.

(3) Emergency action for circumstances that exists such that noncompliance with this ordinance poses an immediate danger to public health, safety and welfare, or the environment as determined by the city. The city will take every reasonable action possible to contact and direct the applicant to take any necessary action, prior to the city taking action.

(c) Reduction of financial security. If requested by the applicant, the amount of the financial security may be

reduced by the city. Said reduction will be based upon the extent to which the grading and restoration have been

9

completed and shall consider the continued need for erosion control. At no time prior to final completion, as defined in section 7-16, shall the security be reduced to less than ten (10) percent of the total original security amount.

(d) Final release of financial security. Any unspent amount of the financial security deposited with the city for faithful performance of the plans and specifications and any related remedial work will be released after the completion and inspection of all such measures and the establishment of final stabilization, as defined in section 7-3, for the permitted site or common plan of development or sale. Sec. 7-9. Amended land disturbance permits. Any changes desired to be made to the land disturbance plan by the applicant following the issuance of a land disturbance permit shall be submitted to the city for review. No changes may be implemented by the applicant unless approved by the city. Any desired change to the land disturbance plan shall be supported by information showing the change desired, the reasons for the change, the effect the change would have upon buildings, structures, adjacent property, drainage facilities and patterns. The request shall be accompanied by geotechnical engineering and geology report as necessary. If the changes requested by the applicant are acceptable, the city will issue an amendment to the land disturbance permit. Sec. 7-10. Cuts.

(a) Generally. Unless otherwise recommended in the approved geotechnical engineering and/or engineering geology report, cuts shall conform to the provisions of this section and the City of Woodbury Land Disturbance Plan and Implementation Requirements.

SWPPP Checklist Construction Stormwater Permit Program

Doc Type: Stormwater Pollution Prevention Plan (SWPPP)

C000

Background: This checklist is used by Minnesota Pollution Control Agency (MPCA) staff for Stormwater Pollution Prevention Plan (SWPPP) reviews. It is provided as an additional resource intended for SWPPP designers for construction projects to assure all required elements of a SWPPP are included. Use of this checklist will help you to determine if your SWPPP is complete, though not all checklist items are applicable to all projects. This checklist can be used for all size projects; however, the guidance document “Stormwater Compliance Assistance Toolkit for Small Construction Operators,” contains a SWPPP template designed specifically for small site projects. This guidance is available on the MPCA Construction Stormwater webpage at: http://www.pca.state.mn.us/wfhya5b.

Note - This checklist is for your information and use is voluntary. The checklist does not need to be returned to the MPCA.
